I was having problems last night getting the turning of a heel that I am making up on my own (sort of....will explain this at a later time), so I did several Google searches (don't ya just love Google????). I did searches for: free sock pattern generator and free knitting software. Though I found some free things for sock pattern generators but not much under free software (of course). If you simply do a search for sock pattern generators you come up a list of websites. Now the software I found was not really free (except for Demo versions or somje small organizing type tools) but they seem to be decent and affordable.
Oh...my guy has a blog now...so hereis a shameless plug for him here: "RenoGeek.com Blog"
